support for de-commissioning a node using 'remove-brick'
to achieve this, we now create volume-file with
'decommissioned-nodes' option in distribute volume, then just
perform the rebalance set of operations (with 'force' flag set).
now onwards, the 'remove-brick' (with 'start' option) operation tries
to migrate data from removed bricks to existing bricks.
'remove-brick' also supports similar options as of replace-brick.
* (no options) -> works as 'force', will have the current behavior
of remove-brick, ie., no data-migration, volume changes.
* start (starts remove-brick with data-migration/draining process,
which takes care of migrating data and once complete, will
commit the changes to volume file)
* pause (stop data migration, but keep the volume file intact with
extra options whatever is set)
* abort (stop data-migration, and fall back to old configuration)
* commit (if volume is stopped, commits the changes to volumefile)
* force (stops the data-migration and commits the changes to
volume file)
